Do aliens look like this? Or like us? What are we doing to find aliens?
The search for ET is taking us deeper into space.

So far more than 100 planets have been spotted among these stars although none of them look like a good place for ET to live.

Beagle 2 is the first British lead mission to Mars. It will be looking for signs of aliens - by sniffing the air for alien farts!

"If there is an organism somewhere, it might be a 1000 mils away, doing it's thing, then it will produce waste products.

"The whole of the atmosphere will pass over Beagle and it will sit there and sniff it. We're calling this the baked beans experiment!" explained Beagle Mission scientist Colin Pillinger.

Many environments are too harsh for life to exist in, so Beagle 2 will be tunneling underground.

But if there are any really clever aliens out there a space program called SETI - Search for Extra terrestrial Intelligence - hopes to be the first to know using telescopes.

So far we've heard nothing from ET and his friends but that may be because our technology is not good enough yet.

Our chances of picking up signs of alien intelligence are about to improve though - as SETI is now building 350 new telescopes to scan more stars than ever.
